THOMAS S. BENNETT, OF ATTLEBORO,

BAND FOR BRACELETS.

Application filed May To all whom it may concern:

Be it known that I, Thomas S. BENNETT, a citizen of the United States, residing at Atlleboro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Bands for Bracelets, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to bands for bracelets of the lazy-tongs type, and is an improvement upon my former Patent No. 709,195, and has for its essential objects, a minimizing of the number of parts and expense,

facile assemblage of parts, an improved spring action, and pivot-bearing, and superior wearing qualities.

To these ends particularly my invention consists in the novel construction and combination of parts hereinafter described.

In the drawings which form a part of this specification, Figures land 2 are rear and side elevations respectively of a front arm shell. Figs. 3 and 4 like elevations of the front arm plate of the front arm. Fig. 5, a rear elevation of the front arm. Fig. 6, a side elevation of the same partially broken away. Figs. 7 and 8, rear Fig. 9, a section of the same on line a; a: of Fig. 7. Figs. 10 and 11, rear and side elevations respectively of the back arm plate. Fig. 12 a detail view of the spring.

My novel bracelet is formed by striking up from a thin sheet of metal, preferably from plated stock, a shell, a, with the precious metal upon the exterior or convex surface. A plate, b, of the same shape as he sheet is next stamped from thin stock having a hollow hub or hearing, b, projecting from its surface intermediate its length. The ends of the plate, b, have perforations, b, to receive rivets, b whose heads, b, rest against the opposite surface of the plate from the bearing, b. The plate, b, is placed withinthe shell, resting against the front wall thereof. The margin of theshell is then turned over upon the plate, 'b, forming a flange, c, which retains the two parts in engagement, as shown in Figs. 5 and 6, and completes the front arm. The next step in the formation of the band is to engage the plate of the back arm to the front arm. The back arm plate, d, as shown in Figs. 10 and 11, is cut from sheet metal and has per- Specification of Letters Patent.

forations, (1, near its ends adapted to receive the rivets, b It has around which is a sleeve, d integral withthe plate, (1. This plate is laid upon thefront arm, the parts being I the collar or hub, d ,loosely mounted on the bearing, b, and having the rivets, b projecting through the opening, d. The bearing, b, is longer than the collar, 1 and the projecting portion of the former is by any convenient tool turned outwardly to form a retaining flange, e, as shown in Fig. 14. The ends of the rivets, b which project through theplate, d, are riveted over with a riveting tool to form the heads or enlargements, f. Theengaging op ,erations above described are performed upon the entireseries of arms extending throughout the length ofthe band, the parts being laid for this purpose in a hori- PATENT OFFICE.

also an opening, J midway its length,

It now remains only-t0 apply the rear'shell which completes the back arm tothe ,plate, d. The, rear shell, h, is cupped'up from a sheet of preferably plated sheet metal, with the precious metal upon the exterior. The margin is cut away to form a flange, h, and shoulder, h The flange is transversely sawed or cut at points, b upon both sides of the shell, near its'middle. The cut portions form ears, h, which as shown in Fig. 15, are bent down upon the, plate, (1. The flange, h, however, is folded upon itself, with its margin resting upon the shoulder, h. arm shells insures a fine finish to band when viewed from the front, as in Fig. 19, where the ears, h, are obscured, and no base metal edges are exposed to view or invite discoloration of the adjacent plated surfaces. The free ends 9 and g of the spring press reflpectively against the sides of the shells, h and a.

By the above construction, it will be observed that the spring retaining plates, rivet plates, and auxiliary plates of my former inventionare 'mple and more secure central pivoting device is'employed; and that the described structure permits a more speedy and convenient assemblage of the parts. My novel structure also presents a smooth, unseamed, plated surface to the arm.

What I claim is,

to each other, each palr of arms comprising first, a front arm provided with rivets upon its ends, a tubular bearing This treatment of the margins of the rear dispensed with; that v projecting from the face ofsaid arm intermediate the end rivets, and second, a back arm provided with means for receiving the rivets, and a hub loosely mounted upon the tubular bearing, and third, :1 spring within the tubular hearing having free ends which bear against the walls of both arms.

.5. A lazy-tongs band composed of pairs of arms pivoted to each other, each pair of arms comprising first, a front arm comprising a shell having a marginal flange, a rivet carrying plate engaged by the flange, and provided with perforations in its ends to receive the rivets, a hollow bearing projecting from the plate, and second, :1 hack arm comprising a shell provided yvith marginal ears, :1 plate retained in the shell by the marginal ears and provided with openings for the rivets, a hub upon the last mentioned plate loosely mounted on the bearing, and third, rivets Mop? 7- pussing through the openings of both plates, and heads.
